BW & Sweep Menu
The bandwidth menu includes functions that control sweep speed and accuracy, and has the
interface for customizing sweep triggers.
When two signals are separated by a freq distance equal to the Resolution BW, a 3 dB dip
between them will appear on the screen. This is the minimum resolvable frequency spacing.
The menu selections legend displays the current value.
Signal Representation
Lowering the RBW will lower the noise floor, which can make low-power signals easier to see,
and makes readings close to the noise floor more accurate.
